Port of Olympia

Olympia, WA

For more than 50 years, Cascade Pole and Lumber Co. (now a subsidiary of McFarland Cascade Holdings, a national decking manufacturer) has produced creosote-treated fir poles for telephone and electrical lines and other commercial uses. Cascade Pole operated its plant on a site owned by the Port of Olympia and adjacent to the popular Swantown Marina on Budd Inlet (part of the Puget Sound). After Cascade Pole vacated the property, the Port was charged by the Department of Ecology with cleaning up recovering the site. Cleanup actions included removing more than 50,000 cubic yards of contaminated marine sediment, completing a barrier wall and modifying the stormwater drainage system to prevent contaminants from entering Puget Sound, conducting a pilot study to evaluate potential treatment methods for the most severely contaminated soils, and capping the area to isolate the public from the contaminated soil.

Hatton Godat Pantier was brought in by the Port as the lead consultant to provide design for the capping operation with an eye towards reclaiming the space as a useable public area.
